I have a Skar Audio SK-1500.1D wired down to 1 ohm on a Fi Audio BL 15'' in a ported box 3.25cf. I need help setting the the Low Pass Filter and the Subsonic. Here are the specs, Low Pass Filter @24dB Slope : 35~250Hz, Subsonic Filter @24dB Slope : 10~50Hz And if it helps i mostly listen to hip hop/rap. Right now idk whats its set to but when i turn the sub up it sounds like the sub is bottoming out?
